METHODS AND SYSTEMS FOR SCALABLE VIDEO CODING WITH MIXED INTERLACE AND PROGRESSIVE CONTENT

摘要

Methods, apparatus, and systems for video coding/decoding are disclosed. One representative method includes a decoder receiving video content including at least a base layer (BL), an enhancement layer (EL) and phase information. The phase information includes an indicator indicating one or more sets of phase parameters from among plural sets of phase parameters. The method further includes assembling the BL into an inter-layer reference (ILR) picture based on the video content and the received phase information, selecting one or both of the ILR picture or an EL reference picture, and predicting a current EL picture using the phase information and one or more of the selected ILR picture or the selected EL reference picture.
